That’s a very fitting term to describe one of the world’s largest cruise ships: the Royal Caribbean Oasis of the Seas. With capacity for a whopping 6,000 passengers and 2,300 crew members, this ship feels like a floating metropolis.

Roam through 7 distinct neighborhoods spread across the ship. First, drop by the Pool and Sports Zone, which includes surf simulators, and then browse the boutique shops along the charming Royal Promenade. The Entertainment Place features Broadway shows while the Youth Zone is equipped with a science lab and plenty of games for kids.

But one of the most impressive parts of the Oasis of the Seas’ layout is Central Park. This lush retreat is the first-ever living park to set sail, with more than 1,200 species of plants. And it’s not the only unique amenity on this ship. The sprawling AquaTheatre is the world’s first amphitheatre at sea. Here you can take in an array of different nautical-themed shows.

And the best way to understand everything that this amazing ship offers is to see if for yourself. This video offers more details.
